Description

Double-foot fixing device for nuclear medicine imaging

Technical Field

The utility model relates to a nuclear medicine detects auxiliary assembly technical field, specific is a nuclear medicine video picture both feet fixing device.

Background

Nuclear medicine (nuclear medicine) is a subject that studies the application of nuclear technology in medicine and its theory. Nuclear medicine imaging relates to a plurality of systems such as center, circulation, skeleton, endocrine and the like, wherein the requirements of whole body bone imaging and tumor imaging on the body position of a patient are strict, the body position placing is an important link in the bone imaging quality control management, the correct body position placing not only reflects the strict employment attitude of medical staff, but also more importantly enables the bone diseases to be completely and naturally displayed on a screen, and the diagnosis of the diseases is improved.

Bone imaging is a highly sensitive but less specific examination, and because of its inaccurate anatomical positioning, it is often necessary to perform local bone imaging or tomographic imaging based on whole body bone imaging to correctly display the location, number, size and form of the lesion, and the position of the bone imaging depends on the suspicious lesion location. If the back position of the thoracic vertebra is raised by adopting the shoulders, the focus can be judged to come from the scapula or the rib; when the radioactive abnormality appears in the sternum or the thoracic vertebra, the front and back oblique positions are adopted to judge the focus part; lower thoracic vertebra and lumbar vertebra pathological changes are taken, and the specific parts of the vertebra, such as the vertebral body, the vertebral arch and the facet joint, affected by the pathological changes can be judged by adopting the backward oblique position; when pathological changes exist at the pubic part covered by the bladder shadow or symptoms exist at the suspected pubic part and the periphery, local bone imaging or tomography at the front and back positions and the lateral positions is carried out; when the tibia and the fibula are suspected to be diseased, the toes of the feet are opposite to distinguish the tibia and the fibula.

When the normal person naturally relaxes both feet, the toe can be seen to be outstretched and the heel can be seen to be adducted, which is in the shape of an inverted eight-character. The standard body positions used for nuclear medicine imaging are: the toes are aligned, the heels are separated, the five fingers are closed, and the palms face downwards. The posture of tiptoe alignment and heel separation can ensure that the long axis of the femoral neck is exposed under the detector to the maximum extent in a normal state, which is beneficial to displaying hidden focuses and is also beneficial to obviously separating and clearly developing the anatomical positions of the front and back overlapped tibiofibulas in the normal state. The five fingers are closed and the palm is downward, which is favorable for clear dissection of the radius, ulna, metacarpal bones and phalanges. In a non-standard position, tibiofibular images are overlapped, and focus is unclear; in the standard posture state, the tibiofibula images are separated clearly, and the focus is displayed clearly. The use of bipedal auxiliary fixtures should, among other things, keep the patient in a standard position:

1) examinations with special requirements on the body position to be taken (e.g. bone imaging);

2) the old and weak patients with poor tolerance, especially the patients with tumor bone metastasis, have obvious pain and are not suitable for maintaining the same posture for a long time;

3) cerebral infarction and mobility impairment.

The imaging time of bone imaging is generally 10min, which requires the patient to maintain the posture by contracting, tightening and coordinating the muscle group of the lower limb, but in the actual operation, most of the patients with the indications are tumor patients or old and weak people, and the patients have poor physique, so that the patients are difficult to maintain the same posture for a long time, further the image quality is reduced, some patients even cover or miss real focuses, and great troubles are brought to clinical diagnosis. In this situation, the best clinical treatment is repositioning and re-collection, which wastes time and increases patient intolerance.

[ example 3 ]

As shown in fig. 3 and 4, on the basis of the above embodiments, the connecting portion of the present embodiment is a hinge structure, and the two supporting plates can adjust the opening and closing included angle by using the hinge as an axis;

the connecting part is provided with a ratchet mechanism, the ratchet mechanism comprises a ratchet wheel and a pawl, the ratchet wheel is coaxial with a hinge of the connecting part and is fixed on one support plate of the bracket, the pawl is fixed on the other support plate of the bracket, and the ratchet wheel and the pawl are installed in a matched manner;

the ratchet mechanism is provided with a switch, and the switch is arranged on the pawl and used for controlling the opening and closing between the pawl and the ratchet;

the bottom of extension board is equipped with the chimb, and this chimb sets up along the bottom edge of extension board.

In use, as described in example 1, the patient's feet were first fixed to the plate and the upper part of the feet were covered with an elastic bandage; the opening and closing angles of the two support plates are controlled by the patient or adjusted by medical staff, and the feet of the patient tend to the most standard detection body position by combining the conditions of different patients. As shown in the figure, the hinge arranged on the connecting part is used for connecting the two support plates, so that the two support plates can be opened and closed to adjust the included angle. The ratchet mechanism shown in the figure is used for preventing the two support plates with the opening and closing angles adjusted from being restored to original shapes and the included angle from being reduced, so that the imaging is unclear. Further, the pawl is provided with a torsion spring or a tension spring so that the pawl is always attached to the ratchet wheel.

The main reason for the above problems is that the fixing device has a main action point on the upper part of the feet of the patient, the heel part is attached to the support plate, but the fixing device has a weak supporting effect on the heel part, and the elastic bandage on the upper part of the feet has a certain deformation capability, so that the feet may move. The chimb is heightened with patient's heel portion, makes the support strengthen the holding power of eight characters in to both feet, and patient's both feet can keep same state for a long time, and difficult emergence is rotated, or is removed.

[ example 4 ]

As shown in fig. 5, on the basis of the above embodiment, the support of the present embodiment is provided with a knee-limiting device, which comprises a groove, the groove is arranged between the legs of the patient, the rear end of the groove is fixed on the support, and the front end of the groove extends towards the crotch of the patient; a pair of ring hooks is arranged on two sides of the groove and corresponds to the knee position of the patient. Further, if the bracket adopts the structure as in embodiment 3, namely the bracket consists of two support plates, and the connecting parts at the tops of the two support plates are movably connected by hinges; the bottom of the bracket is not provided with a bottom plate, the groove cannot be arranged on the bottom plate, therefore, the rear end of the groove is provided with a suspension rod, the suspension rod suspends the rear end of the groove on the connecting part, namely on a rotating shaft of a hinge of the connecting part, and the suspension rod is independent of the support plates on both sides, namely the suspension rod is not contacted with the two support plates. Furthermore, the hanger rod can be designed to be adjustable in length, so that the height of the rear end of the groove can be adjusted, and a urine bag of a patient can be conveniently placed at a lower position relative to the patient, and the urination is smooth. In the scanning detection process, the parts such as the urine bag, the urine tube and the like are overlapped with the part to be scanned of the patient due to disordered placement, so that the scanning result is influenced; therefore, the urinary catheter can be placed in the groove, and the urinary bag is placed in the hollow cavity in the bracket, so that the urinary bag, the urinary catheter and the like are separated from the legs and the feet of the patient without influencing the scanning result.

The groove not only serves as a supporting component of the knee limiting device, but also can be used for containing a urine bag, a urine tube and the like of a patient in the groove, so that the bone imaging is prevented from being influenced due to the disorder of the urine bag, the urine tube and the like. As described in example 3, when scanning for detection, which is generally 15 minutes or more, patients suffer from diseases, and the compliance thereof is sometimes poor, and may be psychological or physiological. As described above, the patient needs to keep the posture by tightening the leg muscles for a long time at the time of examination, which is unstable. According to the knee limiting device, the knee limiting device is arranged between the two legs of the patient, the two legs of the patient have an acting point by sleeving the ring hook on the knee or the lower leg of the patient, and therefore the standard inner splayed body positions of the two feet can be kept in a relaxed state.
